Looking forward to better quality content from this channel! This video is a great start to a great series.

[@mortifyd4805]

I couldn't agree more. This channel could've had TONS of content in the past.

Finally, somebody mentioned rj45 for stranded and solid wire connectors 👍

[@RelativisticVelocity]

I always thought the floss was there for pull strength to relieve stress on the copper when pulling long distances, never considered using it to to remove the jacket.

[@danielgreen414]

Great educational content. People take for granted basic knowledge and rarely share the basics. Thank you.

[@geoffswan1254]

Informative video. Should probably also have mentioned that pin 1 of the RJ45 is the leftmost pin when the connector is held vertically with the pins facing you, and that this is the orange/white wire for 568B cabling.

[@ThiagoNunesRS]

The videos is getting better. Very good!

[@ManjunathCV]

Simple and to the point. Great video!

[@ianluedke]

I can't wait for the rest of the series! Thank you ubiquity these episodes will be VERY helpful. Thank you!

[@Deraco1]

Nice video, however, Sean never specifically mentioned the orientation of the RJ45 connector (He did it on video but never went though why). This is NOT required for most, due to Auto-MDIX, but this is an important thing to know The pins are suppose to up face when putting the wires in. Pin 1 is first from the left when pins are facing up. For T-568-B, that's Orange-White. I noticed two of the graphics, the pins were wrong the first time, then they were right the second time.

[@crystalyzzed]

Ditch all other paid channels and focus on this type of content! This is great. Been installing Ubiquiti products for 6 years and this type of content is great for newcomers to get familiarized. Other consumer, anecdotal oriented content is garbage IMO.

[@pamelawebber7266]

I learned with this type of crimp and rj45, but I have found the pass-through clips/crimper much easier to use. Great instructional vid though, good job!

[@ryoohk]

Pass-through are very nice but only time you dont want to use them is when the jack is shielded but then you will also need to use a shielded rj45 and cable

[@Sam_420]

EZ-RJ45 jacks, are a lifesaver

[@mpxz999]

These are fantastic videos. You sir, know what you are doing! This is the best content that Unifi has ever released. Perfect

[@emp7y]

Awesome video, can't wait for the rest of this series.

[@snoks]

Thanks for the explanation!

[@michaelkosma653]

Very nice. As a rule I never use wire that my cable stripper might have touched. Use the pull string to remove the sheath from the length you need to work with and discard where the cable stripper or scissors or knife was used. Even a small nick or pinch in a solid copper conductor can cause problems later.

[@mvandrei]

This is awesome! it would be great if you could add thumbnails of tutorials inside the controller, for different tasks. This would help a lot, and attract even more customers to switch to Ubiquiti. Also, inviting customers to tell their stories, and how it changed/improved their business would be also a good idea IMO. For example, I loved the live chat feature, the option where the tech support did certain tasks (faster than explaining them), and by watching how it was done, I didn't have to go back and ask for support ever again (for that certain feature setup).

Super useful! Thanks for making this video.

[@ryoohk]

Another tip. To help untwist the wires you can use part of the jacket you strip off and push it between the pairs so that one wire goes in to the jacket and the other stays on the outside you can just twist the jacket in your fingers and it will slide down the pair and help untwist them easier.

[@isaackvasager9957]

huh? That sounds hilariously over complicated.

[@cfgdr3]

@@isaackvasager9957 I've tried this method and it works surprisingly well.

[@isaackvasager9957]

@@cfgdr3 up can literally just twist the pair with your fingers to untwist it. Why overcomplicate it? Lol. I go hundreds of these every year. Takes seconds.

[@bartosz_nowak]

Please add that RJ45 pos1 is always on the left side of the plug looking from cable side. Please explain RJ45 Jack pos1 vs. pos1 in RJ plug.

[@michaelzera9361]

Very well done. Super informative. Great job!

[@chipid4571]

I love ubiquiti👍

[@timrutter]

6:53 The (solid/stranded) lables for the RJ45 crimp types graphics are reversed. Stranded core is used with the top blade type, while solid is used with the lower fork type. I’ve seen professional installers incorrectly use the wrong type! Which will later cause connection issues due to bad connections.

[@hitman132i]

I just been doing low voltage for only 15 years. But I was told by people with more experience that always try to use the dental floss (ripcord). But maybe it's more important for terminating to a jack or patch panel where the jacket is not supported and camera ends.

[@hitman132i]

I like this video to use as a training aid. Looking forward for the rest of the series.

Why i am able to give one only one like to that video? Amazing quality content.

[@typealt]

Pretty sure he uses a pass-through crimper, but not a pass-through RJ45 plug. Also, be sure to get the right RJ45 for your cable. An RJ45 rated for Cat6 doesn't sit well on a Cat5e cable. Also, always test your cables after making them!

[@isaackvasager9957]

There is nothing wrong with using a pass through crimper on non pass through plugs.

[@sgomezroman]

[@jaydmorales23]

4:46 yes to my knowledge there are many different styles of strippers out there,

[@FirstLastOne]

I remember back in the day late night on a Fridays after work spending the evening getting some electrical and network cabling laid at home. You'd build up quite the thirst during the summer months doing that... Oh yeah, Friday nights, strippers and coke. Fun times!

[@nexushexus4365]

[@DeepakSelvarajR]

@Ubiquiti When can we expect the next two episodes?

[@helloruiz]

Don't CAT5 and higher have the same number of wires/pairings (8 wires, 4 pairs)? If so, what about CAT5 makes it unable to transmit 10Gb speeds?

[@ttss5726]

You can achieve 10g over cat5 with the right equipment and short distances. Its not easy but you can. cheaper to run the bigger cable

[@mrchow3233]

The other person already answered the question, so i’m going to skip that part. But some differences, cat5 can support up to 100mhz bandwith capacity, where as cat6 can support up to 250mhz. Another difference is that cat6 cable is more tightly wound, and have more twists. Also, a lot of the cat6 include nylon spline. Not required with cat5 cables, but some manafactrures include it.

[@isaackvasager9957]

Cat6 and up have larger copper conductors (lower gauge), more twists per inch, and sometimes a plastic separator for the pairs.

[@handelhumphrey8596]

Awesome

[@edbpadilla]

Hi! Can you showor explain a 10gig network deployment with unifi devices? Thanks!

[@kharmastreams8319]

Cat5 is maximum 100mbit. Cat5e on the other hand is max 1000mbit

[@MiltonGeorges]

Now show what a pain in the ass it is to work with shielded Cat6A :)

[@tysons6437]

haha. and please don't use pull throughs

[@FirstLastOne]

CAT5e is good to 2.5Gbps to about 50 metres and if you run it correctly, maybe even up to 75 metres.

[@tysons6437]

amen. Thank you! I realize may not be best practice, but the text book isn't always right is my point!

[@revo2maxx]

Really, Why is it that people fail to mention one of what I feel is most important things to Cat Cabling? I mean ok so you guys use CMP so there is no Questions but what about all the Trash that is being SOLD TODAY WITH CCA... Why is it that people don't point out that people need to buy Good Quality cable from a Good Manufacture and be careful about buying JUNK CCA.. There are so many people out there that are selling JUNK cables that should not be used for POE and will or can damage High end POE cameras is people buy JUNK cables.. Knowing is half the battle Also now people are getting even more funny with cables calling Siamese cables Solid Copper core but has no real copper in the power wires and or the video ground.. Buy from a Trusted company. If you are going to pay someone to install your Cameras or Network hardware. If you have a large job and they are doing it for Cheap then I doubt your getting good cables.. Bad Cabling = Nightmare down the road.

[@isaackvasager9957]

You wrote an entire essay instead of simply saying..."Careful not to by Copper Clad Aluminum (CCA) and make sure what you buy is solid copper"

[@kingsleytechconsultants3361]

What the actual hec? This video says "CAT5" is capable of 1G????! NO CAT5E is capable of that not CAT5. I'm I missing something?

[@electroplank587]

to be fair cat5e is the common standard as cat5 isn't sold / manufactured anymore. most installations will be using cat5e so it's fairly accurate within the last 15 years at least.

[@kingsleytechconsultants3361]

@@electroplank587 totally! I was guessing it was just some "Tech talk". When I'm on the job I say CAT5 or CAT6 to my guys and they know what I mean. Unless I point out that it is literally CAT5 NOT CAT5e but for the layman and honestly in a Video I think it should be specified. Not splitting hairs here great video! *Subscribed P.S. I've tested a CAT5 cable at 15 feet and it got 1G. With a $3000 Fluke tester so WTH does it all mean? LOL

[@ChristianMcDonald]

Do people really still terminate RJ45 by hand anymore? Keystones + pre-terminated patch cables are orders of magnitude faster and produce a way more consistent product.

[@MichaelReed135]

Low voltage wire jobs. Can’t fit a terminated wire through a 3/8 hole, especially in 2-3 hundred foot runs. We terminate thousands of cat6 a week. Not fun but it’s still a consistent product.
